Description

Technical Field

[0001] This utility model relates to the field of steam generator technology, and in particular to a steam generator for dehumidifying wet steam. Background Technology

[0002] A steam generator is a device that heats water to produce steam. Steam containing moisture is called wet steam. High moisture content in wet steam affects thermal efficiency and equipment lifespan, thus requiring dehumidification. Currently, wet steam is separated from water by passing it through perforated baffles. The baffles change the steam flow direction, causing the moisture-laden steam to collide with each other. Water molecules aggregate into small droplets during these collisions and flow back to the bottom of the steam generator under gravity, while the steam continues to flow through the perforations in the baffles. To improve the dehumidification effect, several layers of perforated baffles arranged at intervals need to be added between the wet steam inlet and outlet. However, the fixed distance between the wet steam inlet and outlet limits the number of baffles that can be added, thus limiting the dehumidification effect. Furthermore, the alternating arrangement of the baffles increases the overall structural volume, making it difficult to meet the requirements of steam dehumidification operations. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this utility model is to propose a steam generator for wet steam dehumidification. By arranging the first and second discs in a stacked manner, the conveying path of wet steam in three-dimensional space can be extended, thereby increasing the number of wet steam collisions and effectively improving the dehumidification effect of wet steam. It also reduces the overall structural size, making the overall structure compact and effectively meeting the needs of wet steam dehumidification operations.

[0004] The technical solution of this utility model is achieved as follows: a steam generator for wet steam dehumidification, including an upper tank and a dehumidification component;

[0005] The upper tank body is provided with a steam inlet and a steam outlet at both ends along its axial direction.

[0006] The dehumidification assembly is located inside the upper tank and includes several first and second discs that are alternately and sealed and stacked along the axial direction of the upper tank.

[0007] The first plate has a central through hole and several first steam channels extending outward from the central through hole on its front side;

[0008] The second plate has a central blind hole on its front side, and several second steam channels extending outward from the central through hole on its front side corresponding to the first steam channel; the central blind hole is connected to the central through hole of the adjacent upper layer; a connecting hole is provided at the end of the second steam channel on the second plate; the connecting hole is connected to the end of the first steam channel of the adjacent lower layer.

[0009] Several groups of densely arrayed sections are arranged at intervals along their respective extension directions in the first and second steam channels; the densely arrayed sections include several groups of columns arranged at intervals and extending vertically.

[0010] Furthermore, the first steam channel is arranged at an angle, with its lower angle connected to the central through hole; the second steam channel is also arranged at an angle, with its lower angle connected to the connecting hole.

[0011] Furthermore, the steam generator includes a lower tank located below the upper tank; the steam inlet is connected to the lower tank; and the lower tank is equipped with a heating component for generating steam.

[0012] Furthermore, the lowest layer of the dehumidification assembly is a second disc; the upper tank has a bottom plate; the steam inlet is disposed on the bottom plate; the inner bottom surface of the bottom plate is provided with a plurality of third steam channels extending outward from the steam inlet, corresponding to the second steam channel; the end of the third steam channel is provided with a through hole; the through hole corresponds vertically to the connecting hole on the lowest layer of the second disc; the third steam channel is arranged vertically at an inclination, with the upper inclined end connected to the steam inlet; the through hole is connected to the lower tank.

[0013] Furthermore, the steam generator includes a return pipe; the first end of the return pipe is connected to a through hole, and the second end extends into the lower tank and is arranged below the liquid surface of the lower tank.

[0014] Furthermore, the uppermost layer of the dehumidification component is either a first disc or a second disc; the steam outlet is connected to the central through hole on the first disc, or the steam outlet is connected to the connecting hole on the second disc.

[0015] Furthermore, the dense array portion is disposed on the back side of the first disk and the second disk.

[0016] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0017] This invention utilizes a dehumidification component with a first and second disc arranged in an alternating, stacked manner. The first and second steam channels are connected end-to-end to form a steam transport path, thus extending the transport path of wet steam within the three-dimensional space between the steam inlet and outlet of the upper tank. Several densely arrayed sections are arranged within the first and second steam channels to increase the number of collisions between the wet steam and these sections. Water molecules in the wet steam aggregate into small droplets during these collisions and flow back, thereby achieving dehumidification. This method effectively improves the dehumidification effect of wet steam and reduces the overall structural size, resulting in a compact structure that effectively meets the dehumidification requirements of wet steam operations.

[0018] 2. This utility model arranges the first steam channel, the second steam channel, and the third steam channel at an angle, so that water droplets can be guided back into the lower tank, avoiding water blockage inside the dehumidification component, thus facilitating the smooth and stable delivery of wet steam, and is highly practical.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] like Figure 1-7 The image shows a steam generator for dehumidifying wet steam according to this embodiment. This steam generator generates steam. It includes an upper tank 1, a dehumidification assembly, and a lower tank 5. The upper tank 1 has two axially oriented ends. A steam outlet 13 is arranged at the top of the upper tank 1, and a steam inlet 12 is arranged at the bottom. The generated steam enters the upper tank 1 through the steam inlet 12 and is then discharged through the steam outlet 13.

[0030] The aforementioned dehumidification assembly is installed inside the upper tank 1, comprising several first discs 2 and second discs 3 arranged alternately and sealingly along the axial direction of the upper tank 1. The number of first discs 2 and second discs 3 is determined according to actual needs. The outer diameters of the first discs 2 and second discs 3 are adapted to the inner diameter of the upper tank 1. After assembly, the first discs 2 and second discs 3 form a clearance fit with the upper tank 1. In this embodiment, to increase the sealing performance after assembly, a rubber sealing ring can be fitted around the outside of the first discs 2 and second discs 3, and this rubber sealing ring forms a sealing contact with the inner wall of the upper tank 1. After assembly, the end faces of adjacent first discs 2 and second discs 3 contact each other to form a sealing fit. The first disc 2 has a central through hole 21 machined at its center, and several first steam channels 22 extending outward from the central through hole 21 are machined on its front (top) surface. The second disc 3 has a central blind hole 31 machined at its center on its front (top) surface, and several second steam channels 32 extending outward from the central through hole 21 on its front surface; the number and position of the second steam channels 32 correspond to the first steam channels 22. After stacking and assembly, the central blind hole 31 on the second disc 3 communicates with the central through hole 21 of the adjacent upper layer. A through connecting hole 33 is machined at the end of the second steam channels 32 on the second disc 3, and this connecting hole 33 communicates with the end of the first steam channel 22 of the adjacent lower layer. Through the above structural design, each first steam channel 22 and each second steam channel 32 are interconnected end-to-end through the connecting holes 33 and the central through hole 21 to form a steam transport path. The aforementioned steam inlet 12 is connected to the connecting hole 33 of the lowest layer second disc 3, or the aforementioned steam inlet 12 is connected to the central through hole 21 of the lowest layer first disc 2. With the above structural design, steam enters the lower tank 5 through the steam inlet 12, and is then transmitted through the first steam flow channel 22 and the second steam flow channel 32 before being discharged from the steam outlet 13.

[0031] The aforementioned first steam channel 22 and second steam channel 32 are arranged with several groups of densely arrayed sections 6 at intervals along their respective extending directions. Each densely arrayed section 6 has an internal gap channel for steam to pass through. When wet steam passes through this gap channel, the moisture it contains collides with the densely arrayed section 6 and agglomerates to form water droplets. Specifically, the aforementioned densely arrayed section 6 includes several groups of columnar sections arranged at intervals and extending vertically. The size of the gap between each column is determined according to the actual design. The column is a cylindrical structure, and the steam collides with the column during transport. The aforementioned densely arrayed section 6 is fixedly installed on the back of the first plate 2 and the second plate 3. When stacked, the densely arrayed section 6 on the first plate 2 extends into the second steam channel 32 on the adjacent second plate 3, and the densely arrayed section 6 on the second plate 3 extends into the first steam channel 22 on the adjacent first plate 2.

[0032] The steam generator of this embodiment includes a lower tank 5. The lower tank 5 is installed below the upper tank 1. The aforementioned steam inlet 12 is connected to the top of the lower tank 5. A heating assembly 51 for generating steam is installed inside the lower tank 5. This heating assembly 51 is a conventional electric heating device of the prior art. The heating assembly 51 heats water to form steam, which enters the upper tank 1 through the steam inlet 12. In this embodiment, a flared opening communicating with the steam inlet 12 is arranged inside the lower tank 5 to concentrate the generated steam. A water inlet 52 and a water outlet 53 are arranged on the lower tank 5.

[0033] In this dehumidification assembly, the bottom and top layers are both equipped with second discs 3, connecting the steam inlet 12 to the connecting hole 33 of the bottom second disc 3. The first steam channel 22 is arranged at an angle, with its lower end connected to the central through hole 21. The second steam channel 32 is also arranged at an angle, with its lower end connected to the connecting hole 33. The water droplets generated by the collision flow towards their lower ends within the first and second steam channels 22 and 32, and are then discharged from the connecting hole 33 of the bottom second disc 3.

[0034] In the specific structural arrangement, the uppermost layer of the dehumidification component is either the first disc 2 or the second disc 3. The steam outlet 13 is connected to the central through hole 21 on the first disc 2, or the steam outlet 13 is connected to the connecting hole 33 on the second disc 3.

[0035] The aforementioned upper tank 1 has a bottom plate 11. The steam inlet 12 is arranged on the bottom plate 11. A plurality of third steam channels 14 extending outward from the steam inlet 12 are machined on the inner bottom surface of the bottom plate 11 corresponding to the second steam channel 32. A through hole 15 is machined at the end of each third steam channel 14. This through hole 15 corresponds vertically to the connecting hole 33 on the lowest layer of the second plate 3, allowing the third steam channel 14 to communicate with the second steam channel 32. The third steam channel 14 is arranged at an angle, with its upper angled end connected to the steam inlet 12. The through hole 15 communicates with the lower tank 5. Through this structural design, water entering the third steam channel 14 can flow towards its lower angled end and enter the through hole 15. In this embodiment, the aforementioned dense array section 6 is simultaneously installed in the third steam channel 14, and this dense array section 6 is fixed to the back of the second plate 3.

[0036] The steam generator in this embodiment includes a return pipe 4. This return pipe 4 corresponds to the through hole 15. A first end of the return pipe 4 is connected to the through hole 15, and a second end extends into the lower tank 5, positioned below the liquid surface of the lower tank 5. Through this structural design, the returning water enters the return pipe 4 through the through hole 15 and then into the lower tank 5. The return pipe 4 is inserted below the liquid surface of the lower tank 5 to prevent steam from being transported through it.

[0037] In practical use, the wet steam generated in the lower tank 5 enters the third steam channel 14 through the steam inlet 12, and is then transported through the connecting holes 33 and the central through holes 21 in the first steam channel 22 and the second steam channel 32, before being discharged from the steam outlet 13. During the transport process, the wet steam passes through the dense array sections 6, where water molecules collide with the dense array sections 6, aggregating into small droplets that flow back, thus achieving dehumidification of the wet steam. In the above method, the first disc 2 and the second disc 3 are arranged in an alternating stacked manner, and the first steam channel 22 and the second steam channel 32 are connected end to end to form a steam transport path, thereby extending the transport path of the wet steam in the three-dimensional space between the steam inlet 12 and the steam outlet 13 of the upper tank 1. By arranging several dense array sections 6 in the first steam channel 22 and the second steam channel 32, the number of collisions between the wet steam and the dense array sections 6 is increased, improving the dehumidification effect of the wet steam, and reducing the overall structural size, resulting in a compact overall structure. By arranging the first steam channel 22, the second steam channel 32, and the third steam channel 14 at an angle, the returning water can flow back to the lower tank 5 through each of the first steam channels 22, each of the second steam channels 32, and the return pipe 4, thus preventing water from clogging inside the dehumidification components and facilitating the smooth and stable delivery of wet steam, effectively meeting the dehumidification requirements of wet steam.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
